WESLEY BUTLER,

or HILLsBono, ILLINOIS, AssIeNoE 0F ONE-HALF TO J. c.- CRABTREE, 0FTAYLORVILLE, ILLINoIs.

INVALID-CRANE.

and State of Illinois, have invented certain -new and usefulImprovements in Invalid- Cranes, of which the following is aspecification.

This invention relates to devices for the handling of invalids, and hasfor itsprimary object to provide an improved construction, combination,and arrangement of parts in .devices of this character, whereby aninvalid can be conveniently transported from one place to another, andby means of which he can be moved from a reclining position to a sittingposition, and vice versa, thus greatly adding to his comfort.

One of the objects of the present invention is to provide improved meansfor enabling an invalid to be temporarily raised from a bed to permitchange of linen.

Other and further objects will appear in the specification, and bespecifically pointed out in the appended claims, reference being had tothe accompanying drawings exemplifying the invention, and in which,

Figure 1 is a side elevation of a device constructed in accordance withthe princi- ,ples of the present invention, a bed being shown in dottedlines. Fig. 2 is an end elevation of the same. Fig. 3 is a section onthe line 3-3, Fig. 2. Fig. 4 is a top plan view of the same. Fig. 5 isadetail section of the stretcher with its parts arranged for holding theinvalid in a sitting position. Fig. 6 is adetail elevation of thefolding end bar of the stretcher frame. Fig. 7 is a transverse sectionof the'stretcher showing the partis in position permitting thedisengageme'r'itjgf the stretcher sheet from its frame.

-R'ferring more particularly to the drawings and to the embodiment showntherein, a pair of spaced base rails 1 are rigidly joined together by atransverse rail 2, these rails being preferably constructed of tubes.lEachv of the base rails 1 is provided with a pair of pivotally mountedcasters3 adapting the crane to be rolled from place to place I asdesired.

Projecting upwardly from each-"'base rail 1, and adjacent one endthereof, is a tubular standard 4 which is connected with theSpecification of Letters Patent.

base rail 1 by means of a T-couplingi' 5.

Each of said standards is supported from Patented Apr. 21, 1914. Serialm. 641,053.

the base rail by a rear tension rod 6, and a front tension rod 7; saidfront tension rod being disposed beneath a bedstead 8, shown in dottedlines in Figs. 1, 2 and 4. v

Tel'escopically connected with the stand ards 4 are upper tubularsections 9 of similar diameter, the upper end of each standard 4 beingprovided with a gland nut 10, the tension rod 6 being secured to saidgland 10 as shown. in Fig. 2.

Referring now to Fig. 3, means for raising and lowering the sections 9within the standards 4 is provided with an elongated feed rod 11 with acrank 12 at the upper end thereof, ,said rod 11 being journaled at itslower end'within the T-coupling 5. Intermediate of its ends, said rod 11is provided with screw threads 13 which engage the threaded end 14 ofthe section.9 In order to provide efiici'ent means for elevat 'ing andlowering both ends of the section 9 simultaneously, the lower end ofeach rod 11 is provided with a sprocket wheel 15, between whichsprockets runs an endless chain 16, so that any movement of the crank 12transmits power to both rods at once. The upper end of each tubularsection 9 is provided with a gland coupling 17, within which the upperend of each rod 11 is journaled. Projecting horizontally from each gland17 is a horizontal arm 18 provided at its outer end with a suspensionhook 19. Each of said arms 18 is provided with an additional supportfrom the tubular section 9 by means of the strut 20. Secured to eachsection 9 is moreover a suspension rod 21 the lower ends of these rods21 being adaptedlto engage hooks 22 which project from provided with aclaw 29, whereby said sections are held against folding by a downwardmovement of the body 28.. Said sections are, however, foldable laterallyby .moving the pivot 28 upwardly as indicated 30, are end sections 31which, as shown in Fig. 7, are connected by end rail sections 32pivotally connected at 33 and provided with a claw 34 for an exactlysimilar purpose as that described in connection with Fig. 6. There beinga further purpose, however, in that the stretcher body 35 can be relaxedto permit its removal from the but tons or projections 36 projectingfrom the upper edges of the sections 31. Each of the sections 31 isprovided with a plurality of notches 37 along its lower edge to permit astrut 38 to be interposed between the uplift ed section 31 and one endof the outer frame,

and a tension link 39 to support the depending end 31- from the otherend of the outer frame. For this purpose, the outer ends of the outerframe are provided with corre sponding notches 40. The aperture 41 maybe provided in the center of the stretcher body to adapt it to be usedwith a commode-0r bed-pan.

What 1 claim is:

1. In an invalid crane, the combination of a raising device and asupporting frame, said frame being suspended from said rais ing deviceby a pair of links engaging hooks on one side of said frame, and a pairof suspension rods connectingwith hooks on the other side of said frame.

2. In a device .of the character described, the combination with acrane, of a stretcher suspended from said crane, said stretchercomprising an outer frame, and a sectional inner frame, said inner framehaving an intermediate section and adjustable end sec tions, saidcentral sectionbeing rigidly se cured to the side bars of said outerframe,

said end sections being pivoted to said side bars, and folding end railsfor said frames.

3. In a device of the character described, the combination with a crane,of a stretcher suspended from said crane, said stretcher comprising anouter frame,.and a sectional inner frame, said inner frame having anintermediate section andadjustable end sections, said central sectionbeing rigidly secured to the side bars of said outer frame, said endsections being pivoted to said side bars, and folding end rails for saidframes, said end rails being rigidly secured at one end to the side barsof their respective frames and pivotally connected at their adj acentends. 4. In an invalid crane, the combination of a raising device, witha supporting frame, a sectional inner frame carried by said supportingframe, said supporting frame being suspended from said raising device bya pair of links engaging hooks on one side of said supporting frame, andapair of suspension rods connected with hooks on the other side of saidsupporting frame.

5. In an invalid crane, the combination of a raising device, with asupporting frame, a sectional inner frame carried by said supportingframe, said supporting'frame being suspended from said raising device bya pair of links engaging hooks on one side of said supporting frame, anda pair of suspension rods connected with hooks on the other side of saidsupporting frame, the central section of said inner frame being securedto the side bars of said supporting frame, the end sections of saidinner frame being pivotally mounted to said side bars and adjustableupwardly and downwardly, respectively, folding end rails rigidly securedto the ends of said frames, said folding rails providing for thesecuring of a bed sheet to said inner frame.
